With the announcement of Silverlight 2 Beta 2, the Silverlight Dynamic Languages SDK has been updated as well!
Download the Dynamic Languages SDK:
http://www.codeplex.com/sdlsdk/Release/ProjectReleases.aspx?ReleaseId=14254
There's a lot of new stuff here, from new versions of IronRuby, IronPython, Managed JScript, and the Dynamic Languages Runtime, to more sample. Also, there are now three packages: SDK, SDK Samples, and SDK Source.
* SDK: Necessary package to create dynamic language Silverlight applications.
* SDK Samples: a bunch of Ruby, Python, and JScript samples. Best bet is to unzip this in the SDK directory.
* SDK Source Code: If you want to modify the languages/DLR/Silverlight integration, you can do so here, and build using the given Solution file in Visual Studio. This will create a /bin directory with the identical binaries as the /bin directory in the SDK, however without DLL signing.
Enjoy!
